Flexible shaft cleaning has become a useful option for many drainage engineers, particularly when a job calls for controlled mechanical cleaning rather than relying on water jetting alone. In a previous blog, we looked specifically at the Milwaukee M18 High Speed Flexible Shaft Machine and why it can be a smart addition to a drainage engineer’s setup. But the machine or drive method is only part of the picture. The real performance comes from choosing the right flexible shaft cable, chain, head or accessory for the job in front of you. At Jetter Conversions, we stock a range of flexible shaft kits, chains and accessories for different pipe sizes, pipe materials and cleaning applications. Whether you are clearing a blockage, removing scale or tackling heavier internal build-up, choosing the correct setup can make the job quicker, cleaner and more effective. What are flexible shaft cables and chains? Flexible shaft cables are rotating cables used for mechanical drain and pipe cleaning. They are usually housed inside a protective sleeve and powered by a drill or specialist flexible shaft machine. Once inside the pipe, the cable rotates and drives a chain, head or attachment at the end, helping to break down blockages, remove scale, clean internal build-up or prepare the pipework. The cable provides the movement, while the chain or attachment does the cleaning, which is why choosing the right combination is so important. Why the right chain matters Not all flexible shaft chains are designed to do the same job. Some are designed for lighter cleaning in PVC or ABS pipework. Others are built for more aggressive cleaning in cast iron or clay pipes. Some are used for blockage removal, while others are better suited to descaling and cleaning the internal wall of the pipe. This is why it is important to match the chain or attachment to the pipe material and the type of blockage or build-up you are dealing with. Using a chain that is too light may not give you the cleaning power you need. Using a chain that is too aggressive for the pipe material could cause unnecessary damage. The right setup gives you a better balance of cleaning power, control and protection for the pipework. PVC pipes need a more controlled approach When working in PVC or ABS pipes, a less aggressive chain is usually the better option. Plain chains are designed to clean and remove build-up without the hard metal cutting edges found on carbide chains. This makes them a more suitable choice for PVC pipework where controlled cleaning is needed. At Jetter Conversions, we stock flexible shaft kits and plain chain options for PVC pipes, including: Flexible Shaft Blockage Removal Kits for PVC Pipes Flexible Shaft Descale Kits for PVC Pipes Plain chain knockers Circular chain knockers for PVC pipes Mini drain chains for smaller pipework These are useful for drainage engineers dealing with lighter deposits, general build-up and blockages in PVC pipework. Cast iron and clay pipes usually call for a stronger cleaning setup Cast iron and clay pipework can often involve tougher scale, heavier deposits and more stubborn internal build-up. For these jobs, carbide chains are usually the better choice. Carbide chains have hard metal cutting edges, giving them more bite when working against harder deposits. They are designed for more demanding mechanical cleaning and descaling work where plain chains may not be aggressive enough. Our range includes: Flexible Shaft Blockage Removal Kits for Cast Pipes Flexible Shaft Descale Kits for Cast Pipes Carbide chain knockers X-Tip sewer cleaning chains Circular carbide chain knockers Mini drain chains with hard metal tips These products are better suited to cast iron and clay pipes where the job calls for stronger cleaning performance. Blockage removal vs descaling Another important difference is whether you are trying to clear a blockage or descale the pipe. A blockage removal kit is generally used when there is an obstruction or build-up that needs to be broken down to restore flow. A descale kit is more focused on cleaning the internal wall of the pipe and removing scale, deposits or internal build-up. Both use a rotating flexible shaft, but the chain style and setup can vary depending on the job. For example, a blockage removal kit may include chain knockers with drill heads, while a descale kit may use chains without drill heads for controlled internal cleaning. That difference matters when choosing the right product. Choosing by pipe size Pipe size is another key factor. A chain that is too small may not clean effectively. A chain that is too large may be unsuitable for the pipe or difficult to control. That is why many flexible shaft products are listed by both pipe size and cable size. At Jetter Conversions, we stock flexible shaft kits for common drainage applications, including: 75mm (3") to 100mm (4") pipework 100mm (4") to 150mm (6") pipework We also stock individual chains and accessories for different cable sizes, including options for 6mm, 8mm, 10mm and 12mm cables, depending on the product. This helps engineers choose the right chain or attachment for the cable and pipework they are working with. Complete kits or individual accessories? If you are setting up from scratch, a complete flexible shaft kit is often the simplest option. These kits usually include the flexible shaft assembly, rotator shaft socket and the correct chain knockers for the pipe size and material. They are a practical choice if you want a ready-to-use setup for a specific type of job, such as PVC blockage removal, cast pipe descaling or larger pipe cleaning. If you already have a flexible shaft setup, you may only need replacement chains, drill heads or specialist attachments. That is where individual accessories come in. At Jetter Conversions we stock a range of flexible shaft accessories, including: Plain chain knockers Carbide chain knockers X-Tip sewer cleaning chains Drill heads Croco drill heads Croco drain cleaning chains Pipe sanding tools Root cutting heads Chain retrieval tools Mini Mole and Croco Mole accessories This gives you more flexibility when building your kit around the types of jobs you regularly carry out. Useful for jobs where access is limited One of the biggest advantages of many flexible shaft setups is how compact they are. For some jobs, carrying heavy equipment through a building, up stairs or into a tight working area is not ideal. A drill-powered flexible shaft kit can give engineers another option when access is restricted or when a more portable setup is needed. That does not mean flexible shaft cleaning replaces jetting. It simply gives you another tool for the right situation. For drainage engineers, having both options available can make it easier to adapt to the job rather than forcing one method to work every time.

At Jetter Conversions, we only stock equipment that we genuinely believe makes a difference to the way drainage engineers work. The Milwaukee M18 High Speed Flexible Shaft Machine is a great example of this. It’s compact, cordless and built for professional use, giving engineers a really practical way to clean and clear smaller pipework — especially on jobs where access is tight, control is important, or you need something quick and easy to get set up. What is a flexible shaft machine? A flexible shaft machine is a drain cleaning machine designed to clean and clear pipes using a rotating cable and chain attachments. Rather than relying purely on water pressure, the machine spins a flexible cable at high speed inside the pipe. With the right attachment fitted, it can help remove blockages, clean the internal wall of the pipe, and tackle build-up that may be affecting flow. In simple terms, it gives engineers another way to deal with problem pipework. It is not about replacing your jetting machine. For most drainage businesses, jetting will still be a core part of the work, especially for external drains, larger pipework and heavier clearance jobs. But a flexible shaft machine can sit alongside your jetter as another practical option, particularly for smaller lines, internal pipework and jobs where a more controlled cleaning method is needed. Why the Milwaukee M18 High Speed Flexible Shaft Machine? The Milwaukee M18 High Speed Flexible Shaft Machine is designed for clearing clogs in pipes from 32mm to 110mm, up to 23 metres down the line. That makes it a useful option for smaller pipework and day-to-day drainage jobs where access, control and speed matter. One of the biggest benefits is the variable speed. The machine runs from 600 to 2200 RPM, giving you more control depending on the pipe, the blockage and the type of cleaning you are carrying out. That control is important, as drainage work is not always straightforward. Some jobs need a more careful approach. Others need more speed and aggression. Having the ability to adjust the machine gives engineers a better chance of working effectively without overdoing it. It also comes with an integrated mechanical clutch, which helps protect the cable if it binds up. Again, that is the sort of practical feature that matters when you are using equipment regularly on real jobs. Other useful features include: A nylon-coated 8mm cable Universal reception to fit most common attachment heads Electronic foot pedal for control during use Integrated drum brake to slow the drum quickly All-terrain wheels Extendable telescopic handle Durable outer frame Compatibility with Milwaukee M18 batteries From an engineer’s point of view, that all adds up to a machine that has clearly been designed with site work in mind. A useful option for internal pipes and awkward access One of the main reasons flexible shaft machines are becoming more popular is that they are practical. On some jobs, access can be awkward. You might be working inside a property, in a commercial building, in a basement, at the back of a house, or somewhere your van simply cannot get close enough to. In those situations, a compact cordless machine can be a real advantage. The Milwaukee M18 High Speed Flexible Shaft Machine is easy to move around thanks to its wheels and telescopic handle, and because it runs on the M18 battery system, you are not relying on mains power or dragging cables across site. That can make a big difference to how quickly and easily you can get set up. For drainage engineers who already carry out domestic and light commercial work, it gives you another tool for those smaller, tighter and more awkward jobs where a full jetting setup may not be the most convenient first option. Why it can be good for your business From a business point of view, the question is simple: does this help you do more work, keep more jobs in-house and offer a better service? For a lot of drainage engineers, the answer could be yes. If you are already attending jobs, carrying out CCTV surveys, dealing with blocked drains and advising customers, having a flexible shaft machine gives you another way to solve problems while you are on site. That can help your business: Offer a more complete drain cleaning service Deal with certain jobs more efficiently Improve pipe cleaning before CCTV inspections Support descaling and internal pipe cleaning work Reduce the need to pass work on to another contractor Stand out from businesses offering basic clearance only It can also be a good add-on service. For example, if you attend a job and a CCTV inspection shows internal build-up or debris within smaller pipework, a flexible shaft machine may give you a practical way to clean the pipe more thoroughly. That means you are not just identifying the problem. You are offering a solution. And in our view, that is where good drainage businesses continue to grow. The more useful services you can offer, the more value you can provide to the customer. Where it fits alongside jetting The Milwaukee M18 High Speed Flexible Shaft Machine should not be seen as a replacement for a jetting machine. It is better thought of as a different tool for a different type of job. Jetting still has a major role to play, especially for larger pipework, heavy blockages, long runs and regular drainage work. It gives you strong cleaning and clearance power, and for many jobs it will still be the right approach. Flexible shaft cleaning gives you another option. It offers a more targeted mechanical cleaning method, especially for smaller pipes, internal lines and certain types of build-up. Used together, these tools can help you provide a more complete service. You have the power and flow of jetting when the job needs it, and the control and portability of a flexible shaft machine when access, pipe size or the type of blockage calls for a different approach. Who is the Milwaukee M18 High Speed Flexible Shaft Machine for? This machine is particularly well suited to drainage engineers, plumbers and maintenance teams who regularly work on smaller pipework. It could be a good option if: You carry out domestic drainage work You deal with internal pipework and smaller drains You carry out CCTV inspections and want to offer cleaning as part of the same visit You work in properties, commercial buildings or sites with awkward access You want a cordless machine that is easy to move around You want to add another service You already use Milwaukee M18 tools and batteries Why Milwaukee? Milwaukee is one of the biggest and most respected names in professional power tools. The company has been around since 1924 and is known for making heavy-duty tools, accessories and equipment for professional trades. Their focus has always been on durability, performance and trade-specific solutions. That matters because drainage work is tough on equipment. Tools get moved in and out of vans. They are used in difficult environments. They need to be reliable, practical and ready to work when you need them. Milwaukee’s M18 platform is also a major benefit. If you already use Milwaukee cordless tools, there is a good chance you are already familiar with the battery system. The M18 range is built around professional-grade cordless power, and Milwaukee’s FUEL technology combines their POWERSTATE brushless motor, REDLITHIUM battery packs and REDLINK PLUS intelligence to deliver strong performance, runtime and durability. In plain English, Milwaukee builds tools for people who use them properly. And for drainage engineers, that is exactly what you want. Want to learn more?

The best place to start when deciding which jetting machine is right for you is by looking at your business as it is now. Think about the jobs you actually do most often, the size of the drains you usually work on, how much room you have in your van, whether you usually work on your own or with someone else, and whether access is ever a challenge on site. Once you break it down like that, choosing the right jetting machine becomes much more straightforward, because you are choosing based on how you really work day to day.   If you mainly work on 4” and 6” drains   If most of your work is focused on 4-inch and 6-inch drains, our 3008 range  is usually the best place to start. These machines are built for the type of day-to-day drainage work many engineers are doing all the time, giving you strong, reliable performance without stepping into a larger commercial setup that you may not actually need.   From there, it really comes down to how you work and what matters most to you.   If you want a good all-rounder   If you want a good all-round jetting machine, our 3008 Standard Jetting Machine  is a strong place to start. It delivers 3000psi at 8 gallons per minute, is powered by a Honda GX630 petrol engine with a Speck pump and gearbox, and comes with a 250-litre water tank, 60 metres of 3/8" high-pressure hose, 50 metres of 1/2" inlet hose and a built-in antifreeze system. It also has an emergency stop, electric key start and a straightforward on-machine operating setup, which helps keep things simple and practical for everyday use.   For many customers, this is the machine that gives them the best balance. It is ideal for the domestic market, while still being versatile enough for many commercial jobs with the right nozzles. It is also compact enough to work well in a van-based setup without becoming overcomplicated. If you want a dependable van mounted jetting   machine that can cover a wide range of regular work, this is often the one we point people towards first.   If you often work on your own   If you regularly work alone, our 3008 Hardwire Jetting Machine  is well worth considering. It offers the same 3000psi at 8 gallons per minute as the standard 3008, again using a Honda petrol engine, Speck pump and gearbox, but with the added benefit of our hardwire remote system. This setup includes a 50-metre extension reel, a foot pedal and emergency stop,   The reason customers choose the Hardwire is convenience. It allows you to operate the machine from up to 50 metres away, which means you can stay closer to the mouth of the drain or work around the back of a property without constantly going back and forth to the van. For one-man operation, that can make a big difference to how manageable and efficient a job feels on site.   If space in the van matters   If van space is tight, our Compact Jetting Machine  is the option that will make the most sense for a lot of engineers. It gives you the same 3000psi / 8gpm performance as our other 3008 machines, but in a smaller format with a 180-litre water tank and a 200kg dry weight.   If you need to leave plenty of room for other tools and equipment, this machine gives you a powerful setup without taking over the whole van. The lower weight also helps if you are conscious of payload, vehicle wear and fuel use, while still giving you a machine that is more than capable of handling regular work on 4” and 6” drains.   If access is the biggest challenge   Sometimes the biggest challenge is not power or flow, but simply getting a machine where it needs to go. If you are regularly working in places where a van cannot get close enough, our Portable Jetting Machine can be the better fit. It delivers 3000psi at 8 gallons per minute, weighs 135kg, comes with a 150-litre tank, 60 metres of high-pressure hose on a portable reel, and has detachable handles to make it easier to manoeuvre.   We designed this machine for jobs in confined spaces or areas that are not accessible by vans, such as underground car parks, office blocks, train stations and large blocks of flats. It can also be used as both a jetting machine and a jet wash machine with a lance, which adds another layer of versatility.   If your work is moving more into commercial drainage   Once your workload starts moving more into commercial drainage, the type of machine you need usually changes. More demanding jobs often need more water flow, a longer hose and a setup that is designed for bigger pipework and longer runs. That is where the 3012 Jetting Machine comes in. It delivers 3000psi with 12 gallons per minute of flow, is diesel powered, and comes with 90 metres of 1/2-inch jetting hose. It is particularly well suited to commercial cleaning and descaling work on 9 inch pipework where a bigger machine makes a real difference.   This is the machine for businesses that are starting to move beyond mainly domestic work and need something with more commercial capability behind it. If you are finding that the jobs on the diary are getting bigger, heavier or more demanding, the 3012 gives you that next step up without jumping straight to the very top end of the range. It is a sensible move for engineers whose business is evolving and who need their equipment to evolve with it.     If you are regularly working on 9” drains and above   Our 4012 Jetting Machine  is our largest and most heavy-duty machine, built for engineers who spend most of their time carrying out commercial drainage work. With 4000psi at 12gpm, 90 metres of 1/2" high-pressure hose, a diesel Kioti engine and a variable-speed hydraulic reel, it is designed for long runs, larger pipework and more demanding jobs where extra performance makes a real difference.   This machine is particularly well suited to engineers regularly working on 9" drains and above. It comes equipped with the features you would expect from a serious commercial setup, including built-in antifreeze, a low-water cut-out, return valve, water filter, variable throttle and a clear sight glass. If you need serious jetting power from a van-mounted jetting machine, the 4012 is built to deliver it.     Quick guide: which Jetting Machine suits your business?   Scenario Which Jetting Machine Why You want a good all-round machine for day-to-day drainage work 3008 Standard Our dependable all-rounder, ideal for regular use across a wide range of everyday jobs You regularly work on your own 3008 Hardwire   Lets you control the water from up to 50 metres away, making one-man operation easier and more practical You mainly work on 4” and 6” drains but want to save space in the van Compact Jetting Machine Gives you the same strong performance as our standard 3008 in a smaller, more space-efficient setup Access is often the biggest challenge on site Portable Jetting Machine Ideal for jobs where a van cannot get close enough, while still delivering strong jetting performance Your work is moving more into commercial drainage 3012 A clear step up for heavier commercial work, with more flow, more hose and a more capable setup You are regularly working on 9” drains and above 4012   Our heaviest-duty machine, built for larger drains, longer runs and tougher commercial jobs   Want to learn more?   If you would like to take a closer look at our range, click here  to compare the different jetting machines in more detail and see which one could be the best fit for your work.
